1. Express the solution of, x^2 + 6x + 5 ≥ 0, using interval notation. 2. Express the solution of, x^3 + 7x^2 < x + 7, using interval notation. 3. A ball is thrown straight up from the top of a tower that is 280 ft high with an initial velocity of 48 ft/s. The height of the object can be modeled by the equation s(t) = -16t^2 + 48t + 280. Determine the time(s) the ball is lower than the building. Express your answer in interval notation. In two or more sentences, describe your solution method.
